    Subject[RESEND PATCH v3 00/20] mtd: spi-nor: move manuf out of the core
    Date
    From: Tudor Ambarus <tudor.ambarus@microchip.com>

    v3:
    - Drop patches:
    "mtd: spi-nor: Move clear_sr_bp() to 'struct spi_nor_flash_parameter'"
    "mtd: spi-nor: Rework the disabling of block write protection"
    and replace them with the RFC patch:
    "mtd: spi-nor: Rework the disabling of block write protection"
    - rename spi_nor_legacy_init_params() to spi_nor_info_init_params()
    - rebase patches and send them all in a single patch set.

    v2:
    - addressed all the comments
    - all flash parameters and settings are now set in 'struct
    spi_nor_flash_parameter', for a clearer separation between the SPI NOR
    layer and the flash params.

    In order to test this, you'll have to merge v5.3-rc5 in spi-nor/next.
    This patch set depends on
    'commit 834de5c1aa76 ("mtd: spi-nor: Fix the disabling of write protection at init")

    The scope of the "mtd: spi-nor: move manuf out of the core" batches,
    is to move all manufacturer specific code out of the spi-nor core.

    In the quest of removing the manufacturer specific code from the spi-nor
    core, we want to impose a timeline/priority on how the flash parameters
    are updated. As of now. the flash parameters initialization logic is as
    following:

    a/ default flash parameters init in spi_nor_init_params()
    b/ manufacturer specific flash parameters updates, split across entire
    spi-nor core code
    c/ flash parameters updates based on SFDP tables
    d/ post BFPT flash parameter updates

    With the "mtd: spi-nor: move manuf out of the core" batches, we want to
    impose the following sequence of calls:

    1/ spi-nor core legacy flash parameters init:
    spi_nor_default_init_params()

    2/ MFR-based manufacturer flash parameters init:
    nor->manufacturer->fixups->default_init()

    3/ specific flash_info tweeks done when decisions can not be done just
    on MFR:
    nor->info->fixups->default_init()

    4/ SFDP tables flash parameters init - SFDP knows better:
    spi_nor_sfdp_init_params()

    5/ post SFDP tables flash parameters updates - in case manufacturers
    get the serial flash tables wrong or incomplete.
    nor->info->fixups->post_sfdp()
    The later can be extended to nor->manufacturer->fixups->post_sfdp()
    if needed.

    Setting of flash parameters will no longer be spread interleaved across
    the spi-nor core, there will be a clear separation on who and when will
    update the flash parameters.

    Tested on sst26vf064b with atmel-quadspi SPIMEM driver.
